Earl Morcar of Northumbria Fought in the Furd of the Northumbrian Furd

Earl morcar of northumbria was the youngest son of elfgar of mercia. His father had died when he was 11, so there wasn't a lot of time to teach him how to be an english earl. He and his brother edwin were joined by their older brother, who at this time was the earl of mercia,. But where were the men of wessex or east anglia or kent? Where, for that matter, was king harold godwinson? Shouldn't he be up here handling his own messeass family?
